Geological Summary

The Chilcotin basalts form an extensive series of flat-lying basaltic lava flows of Miocene to Pleistocene age covering the interior of British Columbia (Mathews, 1989). The flow remnants form eroded volcanic outcrops that appear to have been erupted from now-eroded coalescing small shield volcanoes scattered throughout the intermontaine region. Most flows are 5-10 m thick, but locally are very thick (up to 200 m) where they fill palaeovalleys. In some instances thick sequences of pillows are found, in other localities they form a thin veneer under glacial drift. The Chilcotin basalts are listed here in two groups--a northern group in the Chilcotin Plateau area, and a southern group in the Thompson Plateau. Eroded volcanic outcrops of Pleistocene age of the northern Chilcotin group are found at Alixton Creek, Big Bar, Browns Lake, Crows Bar, Dog Creek, Prentice Gulch, and Thaddeus Lake (Hickson et al., 1994).
